Jupyter Notebook - install python 2

EDITED

I'm very new to python and have a probably super basic question. I've installed Jupyter Notebook by installing anaconda which includes python 3 by default. Now I want to use an external toolbox which still works with python 2.7, so I'm trying to get e kernel with python 2.7 as suggested here. In the Anaconda Prompt I'm typing

python2 -m pip install ipykernel
python2 -m ipykernel install --user

But it says that it couldn't find the command "python2". Any idea?

I had the same issue. You can try starting jupyter-notebook from python2

$ python2 /path/to/jupyter-notebook

in my case running python2 /usr/bin/jupyter-notebook fixed the issue. enter image description here

shebang in my case

$ head -1 /usr/bin/jupyter-notebook
#!/usr/bin/python3.4
$

I still don't know why it doesn't work, but i found out what worked instead. Using 

conda create -n ipykernel_py2 python=2 ipykernel
activate ipykernel_py2    
python -m ipykernel install --user

in the Anaconda Prompt added the option to open a python 2 notebook in the Jupyter Notebook. Also I can change the Kernel now to python 2.

Have you tried looking at the Jupyter Notebook homepage?

Just use

pip install jupyter

or

pip install jupyter --user
